The 4GB Pulse, which can hold 400 hours of audio, will have a suggested retail price of $199. The 2GB model has dropped to $169, a price Livescribe has recently been promoting on its Web site.

Livescribe added Mac support in November and recently released a software update that also makes its pens compatible with Windows 7. The company said it plans to add an application store for the Pulse later this year.

The company is also expanding the number of places where folks can buy the pens. In addition to current sellers such as Target and Amazon.com, Livescribe will start selling the pulse at Best Buy, select Apple stores and, starting in November, at Staples.

"We know Pulse will excite shoppers and are thrilled to have broadened not only our product line, but also our retail distribution to reach people wherever they shop for electronics," Chief Marketing Officer Byron Connell said in a statement.
